Title: Gamma correcting method for simulator
Inventor: SUZUKI KENJI
IPC: G03B27/32
Filed: 1986-08-06
Abstract: PURPOSE:To improve the S/N ratio, and also, to generate a simulator at a low cost by executing simultaneously corrections corresponding to a gamma characteristic of a CRT and a gamma characteristic of photographic paper. CONSTITUTION:As for a usual TV system, gamma of a TV is set to about 2.2 so that a visual observation becomes satisfactory, therefore, a gamma correcting circuit of (R)=0.45 is provided on a TV camera so as to become gamma=1 as a whole, but in case of a usual print, it is finished so as to be contrasty as gamma=about 2.0. Therefore, a single gamma correcting circuit which has set gamma to about 1 (0.45X2.0) is provided in a simulator without providing a gamma correcting circuit in a camera 30, so that a correction corresponding to a gamma characteristic of a CRT and a correction corresponding to a gamma characteristic of photographic paper can be executed simultaneously. In this way, since a single gamma correcting circuit is used, the cost is reduced, and also, since gamma of the gamma correcting circuit becomes about '1', gamma is scarcely varied by the gamma correction in the simulator, and a picture quality of the CRT becomes satisfactory.
